Java Virtual machine problem

[Bas ter Brugge]

Hi,

I'm using:
Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.08-_28_nov_2002_00_09 PA2.0, mixed mode) and keep getting the following exceptions:

implicit exception happened at 7d6af258
Stack_Trace: error while unwinding stack

Anyone knows what's going on?

Hi

Just to test have a go at working around the problem.
Basically by disablingimplicit null checks
Add the -XX:-ImplicitNullChecks option to
the java command line.

Then let us know what happens

Hi

go to

www.hp.com/go/java

get a much later version.

Take care with patches. see release notes

null exception in compiled code looks like the problem ... whether this is a bug or incorrect coding is your actual question ....

If you have a support contract with HP I'd consider using it, otherwise "file core",output if the application drops core,and O/S details and a stack trace may help someone familiar with java on this ....

also command line compile line options may also shed some light here ...

ps did this work wrt any previous version of java NB I'd also urge you to upgrade your version of java too maybe even goto 1.4

Java seems to be something you can install and get working to some degree with out required/recommended patches installed.

Better however to have them in.

My tush is still smarting from doing this backwards myself.

The JVM we previously used was: 1.3.1_01 and everything worked with that one.
